Final Project -- UEP0239 -- Hongkun Huang

1. Environment and Selected data

Summary:

The theme of my project was to explore the most suitable areas for new libraries in the Boston area. Each ZCTA was scored by suitability analysis, and the area with the highest score was the most suitable ZCTA for new libraries. And compare the number of existing libraries in the region to determine the final result.

I utilized a total of six weighting factors, and the areas with the highest scores had the following characteristics: far from existing libraries, mear to universities and general schools, near to bus stops, and a land category of Developed space.

All coordinate systems are adjusted to EPSG:6491

Note: In this analysis, I chose a total of six indicators in BostonMPO area:

  1. distance to existing libraries;
  2. distance to universities;
  3. distance to general schools;
  4. distance to bus stops;
  5. land coverage category;
  6. number of existing libraries in each ZCTA

2. Clip Study Area (Boston Region)

3. Visualize Spatial data (Rasterize / Euclidean Distance / Reclassify / Attribute join)

3.1 Euclidean Distance to Libraries and Reclassify

3.2 Euclidean Distance to colleges and Reclassify

3.3 Euclidean Distance to schools and Reclassify

3.4 Euclidean Distance to Bus stops and Reclassify

3.5 Land Cover Reclassify

3.6 The Number of Library in each ZCTA (Attribute join)

By calculation, there are currently three ZCTAs with the largest number of libraries (3). They are 02138,01960 and 02125

4. Calculate weighted Raster and Suitability Analysis

Conclusion: The highest scored ZCTA is 01731, indicating that a new library is most appropriate in this area. And the number of existing libraries in this area is small, which meets our requirements for new libraries.
